I dont mean to prey upon your misfortune. I have a 800 and 810 and I need a 770 to test code on. I would not be willing to pay more than 50$ though. I am sure you probably are looking for a higher number, and maybe someone will offer one. The offer stands to anyone until I find one. Donations are also accepted Please dont be offended, I am not trying to be a jerk, its just not worth more than that to me. Good Luck!
